Actual experience. Just checked again this morning on the Chrono.

.357 Mag
WW 296
Charge more than Win says, .5 gr under per one book, .5 gr over another book. (I'm backing off .5 gr next time around)

Oregon Trail 125-gr TC: 1517.9 fps, ES 35.8
Hornady 125-gr XTPs: 1432 fps, ES @ 60 IIRC
Win bulk 125-gr JHPs: 1432 fps, ES I don't remember.

So, if it takes MORE pressure to get a higher velocity, which bullet is more likely to be at max pressure?

BTW, half the cases fall out by gravity, shaking alone ejects 4 or 5 out of 6.

I think that's why most manuals show lower powder charges for lead than for jacketed. It's not just a matter of avoiding loads that lead the barrel a lot.
